Hi Davision,
This is not a bug, but rather expected behavior. The engine is not meant to be used like modeling software. When you scale an asset asymmetrically, then try to scale the asset you have modified, the engine scales the asset from it’s original parameters, not the parameters of the newly deformed asset. This is for a number of reasons that deal with the asset’s, physics, collisions, etc.
However, it is still possible to achieve the effect you want by manually entering the scale values in the details panel, which it looks like you were able to do in the picture of the table with the border around it.
Thanks
